TORONTO, ONTARIO–(Marketwired – Dec. 31, 2015) – Banro Corporation ("Banro" or the "Company") (NYSE MKT:BAA)(TSX:BAA) announces that it has signed definitive agreements with RFW (through its affiliate RFW Banro Investments Limited) and with funds managed by Gramercy Funds Management LLC ("Gramercy") for an equity private placement, a term loan facility, and a gold streaming transaction relating to the Twangiza mine, providing total gross proceeds to the Company of US$98.75 million. RFW manages the Baiyin Stream Partnership I, LP, a mining investment fund through which the investment will be made, and which is led by the Baiyin Nonferrous Group Co., Ltd. ("Baiyin"), a strategic Chinese mining group based in Gansu, China. The equity placement and gold streaming transaction are transacted solely with RFW, while the term loan will be funded by RFW and investment funds managed by Gramercy. Contingent on these transactions and in order to create alignment amongst the parties, RFW has also entered into a definitive agreement with Gramercy to purchase US$40 million of the outstanding Banro senior secured notes issued by Banro on March 2, 2012 (the "Senior Notes"), and US$20 million of the outstanding preferred shares issued by subsidiaries of Banro on February 28, 2014.

The closing of these transactions (the "Closing"), which is expected to occur in January 2016, is subject to conditions precedent customary for transactions of this nature, as well as certain necessary regulatory approvals, including the approval of the Toronto Stock Exchange for the private placement. The Company will continue to work with its financial advisor, Long March Capital Limited, in addition to RFW and Gramercy in order to obtain all required approvals to close the transactions. Implementation of RFW and the Baiyin Stream Partnership structures, which is in progress at the time of signing of the definitive agreements, and Baiyin's investment therein are subject to concurrent approval with the transactions.

"We believe the long-term nature of the Twangiza streaming arrangement and private placement, along with the committed strategic relationships involved, will provide Banro with a solid base to achieve its longer term growth objectives as well as the refinancing requirements in 2017," commented Banro Board Chairman, Richard Brissenden.

The term loan facility represents a loan of US$22.5 million with an initial maturity date of November 30, 2016, but which may be extended until November 30, 2019 provided certain financial tests are met. The facility bears interest at a rate of 8.5% per annum for the first two years of the term and then at a rate of the 3 month LIBOR rate plus 8.0% for the last two years of the term, with the interest payable quarterly and the principal repayable in full at the end of the term of the facility. The loan may be prepaid at any time without penalty. At any time following the second anniversary of the loan, the lenders may require prepayment. On Closing, Banro will issue to the lenders a total of 10 million common share purchase warrants ("Warrants") of Banro (5 million Warrants to RFW, which is advancing half of the loan, and 5 million Warrants to Gramercy, which is advancing the other half of the loan), with each such Warrant entitling the holder to purchase one common share of Banro at a price of US$0.2275 until the date which is three years following the Closing.

The Twangiza streaming transaction provides for the payment by the purchaser of a deposit in the amount of US$67.5 million and the delivery to the purchaser over time of a certain percentage (the "Entitlement Percentage") of the life-of-mine gold production from the Twangiza mine (or any other projects located within 20 kilometres from the current Twangiza gold mine) based on the gold price at the time of delivery. The Entitlement Percentage is 11% based on a gold price between US$1,150 and US$1,500 per ounce, 12.5% based on a gold price of less than US$1,150 per ounce, and 9.5% based on a gold price greater than US$1,500 per ounce. Commencing January 1, 2016, once total gold production from the Twangiza mine exceeds 1.14 million ounces, each of the Entitlement Percentages above will thereafter apply at 50% of the above percentages. The ongoing payments to Twangiza upon delivery of the gold are US$150 per ounce. At any time after the third anniversary of the Closing, Twangiza may, at its discretion, terminate the stream by paying to the purchaser in cash a buyback price equal to an amount which would result in the purchaser achieving an implied internal rate of return of 17.5% on the cash flows arising from the stream during the period from Closing to the date that is 12 months following the date of payment of the buyback price.

The private placement transaction provides for the issuance by Banro to RFW of 50,000,000 common shares of Banro and 2.5 million Warrants, for total gross proceeds to the Company of US$8.75 million. These Warrants will have the same terms as the Warrants to be issued under the term loan transaction as set forth above. RFW will hold approximately 16.6% of the outstanding common shares of Banro upon completion of this private placement.

"Baiyin's investment in Banro through our offshore direct investment fund is consistent with our strategy to invest in low cost mines with large gold endowments and substantial growth opportunities," commented Baiyin Chairman, Liao Ming. "We will support Banro in unlocking the considerable potential of the Twangiza-Namoya Gold Belt."

Holders of more than 50% of the Banro Senior Notes prior to the transaction have agreed to provide the required consent to the amendments of the Company's Note Indenture and related Collateral Trust Agreement in order to secure the gold delivery obligations under the Twangiza streaming transaction by way of a "Parity Lien" within the meaning of the Note Indenture. Banro has agreed to place US$26.25 million of the proceeds from the financing in escrow with the trustee for the Senior Notes to satisfy the remaining three interest payments under the Senior Notes through the maturity date of March 1, 2017.

"We are extremely pleased to welcome Baiyin as a key stakeholder in Banro. Through this investment, our strategic interests are substantially aligned as we pursue our mutual objective of supporting Banro so that it may realize its production potential," commented Robert L. Rauch, Senior Partner, Portfolio Manager of Gramercy Funds Management LLC.

The contemplated use of proceeds from these financing transactions include:
